I've had this miner (
http://drillbitsystem.com/shop/bitcoin-miners/avalon-16-by-drillbit-systems/) running for a while now with one 120mm fan underneath and two 80mm fans blowing through and over the heatsink/board. It's adequate cooling, but takes up space, and sounds like a jet taking off.
Is there any other way you'd reccomend cooling it?
I've noticed the chips are exposed on the top, would those tiny heatsinks for the antminers (I think) help at all, or does not much heat go through the top?
Thanks,
